To all lwhom it may concern:

Be it known that we, JOHN R. WINTER and EDWIN C. WINTER, citizens of the United States, residing at Detroit,in the county of VVayne-and State of Michigan,.have invented certain new and useful Improvements in Nuts, of which the following is a specification. v

This invention relates to nuts and the like, and comprises broadly a sheet metal nut stamped and drawn into proper shape by means of suitable dies, and has for itsobject to provide a satisfactory nut which can be made ata smalll cost from sheet metal instead of from the bar metal usuall employed for that purpose. This will resu t in a considerable saving of metal, which is a matter of considerable importance in nuts madeof brass and other highpriced metals. The nuts may be made in any shape desired, that is, either round, square, hexagonal or otherwise, and the inventlon is not limited to the particular shape and construction shown in the accompanying drawings, in which one form of the' invention is illustrated.

In the drawings, Figure 1. is a side elevation of a hexagonal nut constructed according .to the invention, this particular type being a nut particularly `used for'bind'mg posts or,

screws. Fig. 2 is a top planview.V Fig. 3 is a section on the line 3-3 of Fig. 2. Fig. 4 is a bottom planview.

The nut shown herein is produced by sev-Y eral operations from a flat blank which is cut, punched, and shaped by speci/al dies to the form shown and described herein. The method of construction ma beso far explained as to say that a circu ar blank isgrst cupped, the head is punched and the edges turned in to form a central tube, after which the sides are pressed in to form a neck, and the4 arts are then threaded intei'nally to take theolt or screw.

` When completed the nut forms a hollow structure havinga head 6, sides 7, a neck-8 and a flared base 9. The head is punched, .as

stated, and the edges turned in to form atube l- 10 which is internally threaded, as indicated at 11, and a kerf 12 is stamped in the head, extending diametrically across the same. The sides 7 are pressed to the desired shape, and the neck 8 is pressed in so that its inner diameter is substantially e ual to the diameter of the. tube 10, and sai( .inner surface is threaded as indicated at 13, forming, in eiect, a part of the threaded bore of the nut.

The base 9 is spreadto about the same diam-l eter as the head and bindsagainst the workl or surface to which the nut-is applied, the

bolt or screw being engaged by the .threads 11 and 13 within the nut. A nut so formed, or otherwise formed within the scope of the invention, will have suiiicient strength to stand any ordinary strain, even when constructed of comparatively thin metal.

1. A nut made of lsheet metal, having a hollow body the sides of which vare contracted near the base, forming a neck, which is internally threaded.

2. A nut made of one piece of sheet metal,- shaped to form a hollow' body, and having upper and lower internally threaded tubes in
